Manufacturing of a UHF Diplexer Low Noise Amplifier for the UAV Industry

Manufacturing of a UHF Diplexer Low Noise Amplifier

Satellink is an accomplished supplier of state-of-the-art low noise linear amplifiers found in cutting edge applications. We designed and manufactured the UHF diplexer LNA for a customer in the unmanned aerial vehicle (UAV) industry, where lightweight construction, economically-sized packaging, and precision performance are critical. In addition to engineering, we sourced all the required components, assembled the devices, and applied a protective chromate conversion coating. Quality assurance protocols, conducted in accordance with MIL-STD-810, included functional testing as well as dimensional inspections and verification.

Featuring an EMI-shielding aluminum enclosure, this LNA provides transmit-receive functionality from a 5.37" in height, 4.50" in width, and 1.12" in depth package. Weighing only 2 lbs., it operates in the 248 to 270 MHz minimum frequency range and offers a low noise figure of 2.0 dB max. We designed it to withstand temperatures from -55°C to 71°C, 100% humidity conditions, and pressures at altitude of up to 70,000’. It was designed to provide 230,000 hours of stable, reliable operation.
